Another Snowy Week...
First off, thanks for being so patient...we had some in house meetings this evening which delayed this posting. So we are tracking three systems once again this week...the first is in response to milder air working in to the region this will result in some light snow late tonight through late morning...coatings to around 1" of fresh snow is expected. This certainly isn't a big deal but will likely grease up the roads so please be careful.
The second one of the week is the biggie...or at least will be a big ocean storm...we know that much...what we don't know is the final track. By looking at the upper level wind pattern I agree with the major models to keep the low either around Nantucket or even outside of it. A track like that would mean that we actually may miss a lot of the warm advection heavy precip on the front side and that we would be relying heavily on the backside of the storm for the majority of the snow. I'm ok with that especially with the current track of the 850mb low but if that shifts any farther east we'd be looking at a big bust! I also see that over a short distance you are looking at a lot of snow in one area and very little snow in the distant interior...again big bust potential. At the start of the event the air looks marginally cold enough and there will likely be some issues with mixing especially over SE Mass...at the moment I think Boston stays all snow although it will likely be on the wet side especially at the beginning. Precip will start Wednesday evening and continue through the night before ending sometime Thursday morning (early). At this time I could see Boston getting a foot of snow and I could also see them getting 4" of snow...that's how intense the gradient looks to be. Right now we are looking at a 6-12"+ snowfall for most of Eastern Mass except far SE areas...amounts should also rapidly decline in Western and Northern New England. Again, this track is still wobbling a bit and a bit can make a huge difference this time around.
The last snow maker of the week gets us Saturday afternoon into the night...a clipper type system likely to drop a few more inches of snow across the area.
